A bat flies toward a wall, emitting a steady sound of frequency 1.70 kHz. This bat hears its own sound plus the reflected by the wall. How fast should the bat fly in order to hear beat frequency of 10.0 Hz?
Solution 72P Step 1: The bat releases sound frequency of 1.70 KHz = 1700 Hz, which is the frequency sent by the source (f )s But here there are two scenarios. One where the bat is the source and the wall is the receiver and vice versa. The speed of sound is 344 m/s which is the V in the doppler effect equation. By doppler effect the frequency change will be, V +V V +V f = s f0 = s f0-------------------(1) V Vs V Vs
